iphone - How do I detect Mobile Safari server side using PHP?

Question

Mobile Safari is a very capable browser, and it can handle my website as it is perfectly. However, there are a few elements on my page that could be optimized for browsing using this device; such as serving specific thumbnails that are smaller than the desktop counterparts to help fit more content into the screen.

I would like to know how I can detect Mobile Safari (all versions, preferably) using PHP, so then I can serve a) a specific css file and b) different sized image thumbnails.

Thanks Joe, I read that page and found the WebKit detection library (in JavaScript). I changed the code to suit my needs.

For anyone that's interested, here's my solution.

<?php

/* detect Mobile Safari */

$browserAsString = $_SERVER['HTTP_USER_AGENT'];

if (strstr($browserAsString, " AppleWebKit/") && strstr($browserAsString, " Mobile/"))
{
    $browserIsMobileSafari = true;
}

?>
